20642735 ÷ 270 
The aim is to understand the frequency of 270 in 20642735.

Moving on to step 1:
If we divide 2 by 270, we get 0 and a remainder of 2.
Use 0 as the next digit of our solution. 
Result so far: 0.0
If we subtract 0 from 2, we get 2.
Take the next digit (0) from the dividend and append it to 2, then repeat: 20 / 270

On to step 2:
When dividing 20 by 270, we get 0 with a remainder of 20.
Use 0 as the next digit of our solution. 
Result so far: 0.0
The remainder is 20 after subtracting 0 from 20.
Grab the next digit (6) from the dividend, add it to 20, then carry on: 206 / 270

Advancing to step 3:
270 goes into 206 0 times with a remainder of 206.
The next digit of our result is 0. 
Result so far: 0.0
The remainder is 206 after subtracting 0 from 206.
Append the next digit (4) from the dividend to 206 and continue with: 2064 / 270

On to step 4:
2064 divided by 270 is 7 with a remainder of 174.
The next digit of our result is 7. 
Result so far: 7.0
Subtract 1890 from 2064 to get 174.
Include the next digit (2) from the dividend after 174, then repeat: 1742 / 270

Let's proceed to step 5:
When dividing 1742 by 270, we get 6 with a remainder of 122.
The number 6 becomes the next digit in our result. 
Result so far: 76.0
Subtract 1620 from 1742 to get 122.
Take the next digit (7) from the dividend and append it to 122, then repeat: 1227 / 270

Advancing to step 6:
When dividing 1227 by 270, we get 4 with a remainder of 147.
The number 4 becomes the next digit in our result. 
Result so far: 764.0
Deduct 1080 from 1227 and we're left with 147.
Bring next digit (3) of the dividend behind the 147 and repeat the process: 1473 / 270

Let's proceed to step 7:
270 can be fit into 1473 5 times, resulting in a remainder of 123.
Put 5 as the next digit of the answer. 
Result so far: 7645.0
Subtracting 1350 from 1473 leaves us with 123.
Bring next digit (5) of the dividend behind the 123 and repeat the process: 1235 / 270

On to step 8:
270 can be fit into 1235 4 times, resulting in a remainder of 155.
Use 4 as the next digit of our solution. 
Result so far: 76454.0
Subtracting 1080 from 1235 leaves us with 155.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1550, and continue the process.

Going ahead to step 9:
270 goes into 1550 5 times with a remainder of 200.
The number 5 becomes the next digit in our result. 
Result so far: 76454.5
The remainder is 200 after subtracting 1350 from 1550.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2000, and continue the process.

On to step 10:
2000 divided by 270 is 7 with a remainder of 110.
The number 7 becomes the next digit in our result. 
Result so far: 76454.57
Subtract 1890 from 2000 to get 110.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1100, and continue the process.

Step 11:
The number 270 fits into 1100 4 times, leaving a remainder of 20.
Put 4 as the next digit of the answer. 
Result so far: 76454.574
If we take 1080 away from 1100, we end up with 20.
Since there are no more digits in the dividend, we add a zero to the remainder making it 200, and continue the process.

Advancing to step 12:
270 goes into 200 0 times with a remainder of 200.
Put 0 as the next digit of the answer. 
Result so far: 76454.574
Subtract 0 from 200 to get 200.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2000, and continue the process.

Going ahead to step 13:
270 can be fit into 2000 7 times, resulting in a remainder of 110.
The number 7 becomes the next digit in our result. 
Result so far: 76454.57407
The remainder is 110 after subtracting 1890 from 2000.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1100, and continue the process.

Moving on to step 14:
The number 270 fits into 1100 4 times, leaving a remainder of 20.
The next digit of our result is 4. 
Result so far: 76454.574074
Subtract 1080 from 1100 to get 20.
Since there are no more digits in the dividend, we add a zero to the remainder making it 200, and continue the process.

Advancing to step 15:
200 divided by 270 is 0 with a remainder of 200.
The next digit of our result is 0. 
Result so far: 76454.574074
If we subtract 0 from 200, we get 200.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2000, and continue the process.

Advancing to step 16:
270 can be fit into 2000 7 times, resulting in a remainder of 110.
Record the quotient 7 as the next digit in the result. 
Result so far: 76454.57407407
Deduct 1890 from 2000 and we're left with 110.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1100, and continue the process.

After the division, we end up with 76454.57407407 and a remainder of 1.1e-07.
